Ladder logic is the first in a series exploring different software programming methods how to choose the most appropriate model of computation based on system requirements and architecture. Future articles will cover textual, function block/data flow, state chart, and simulation and modeling methods.
Ladder. A ladder is a vertical or inclined set of rungs or steps. There are two types: rigid ladders that can be leaned against a vertical surface such as a wall, and rope ladders that are hung from the top. The vertical members of a rigid ladder are called stringers or rails or stiles.rinceton's WordNet (0.00 / 0 votes) Rate this definition: ladder (noun). steps consisting of two parallel members connected by rungs; for climbing up or down. ladder (noun). ascending stages by which somebody or something can progress. he climbed the career ladder. run, ladder, ravel (verb).
